热声压缩机的实验研究

Experimental Study on a Thermoacoustic Driver

近年来，利用热声原理研制而成的热声压缩机是一种新型的压力波发生器，它整体无运动部件、光滑动密封，具有结构简单、运行可靠和寿命长等优点。本文介绍了一台热声压缩机的实验装置，它主要由高温气库、加热器、蓄热器、水冷却器和共振管等五个部件组成，重点研究了共振管的长度，充气压力和加热温度对压机性能的影响。

The Thermoacoustic driver is a kind of new pressure wave generator based on the ther-moacoustic effect, Having no moving parts and sliding.seals. It is simple, reliable and long -term for the nonmaintenance machine. An experimental thermoacoustic driver was intro-duced. It consists of a hot buffer, heater, stack, cooler and a resonator. The effect of the res-onator length, average pressure and the temperature on the performance of the thermoacoustic driver were presented.
